The Crystal Ball Has Clouded

Last month, Marquette published a Chart of the Week that highlighted the aberrational length of the current Treasury curve inversion. As outlined in that publication, a Treasury curve inversion occurs when short-term rates move higher than long-term rates, and a persistent inversion has historically served as a portent of an economic recession. To that point, an inversion preceded each U.S. recession by 18 months at the longest (usually less than a year) since the 1970s. That said, while the current inversion has persisted for nearly two years (and counting), an economic downturn has yet to materialize. Put simply, this time may be different. In fact, according to a recent Reuters poll of bond market experts, nearly two-thirds of respondents opined that the shape of the yield curve no longer maintains the predictive power it once held.

What could account for this shift? There are a few possible explanations, and the first relates to the long end of the curve. Specifically, long-dated bonds, or those with maturities of 10 years or greater, have experienced a multi-decade bull run due to strong demand from pension funds and insurance companies. These entities utilize longer-dated bonds to hedge liabilities, and demand from these plans helps prevent selloffs during periods of rate weakness. These dynamics have served to keep the long end of the yield curve relatively stable in recent time. Indeed, while the effective federal funds rate has climbed by over 5% since the Fed began its hiking cycle, the 30-year Treasury yield has risen by roughly half that amount over the same period. The second possible explanation is related to shorter-dated bonds, as 2-year Treasuries are quite sensitive to Fed policy. Given recent hiking and the central bank’s commitment to holding its policy rate higher for longer, yields on 2-year notes have been pulled higher and currently sit at elevated levels.

In order for the yield curve return to normalcy, short-term yields must fall more sharply than long-term yields. However, a resilient economy will likely keep short-term rates high, and strong technical factors have likely put a cap on yields on longer-dated securities. Given this situation and the changing market dynamics outlined in the previous paragraph, the historical relationship between yield curve inversions and recessions may not hold in the current environment.
